Criminal Liability of Healthcare Personnel

The criminal liability of healthcare personnel is distributed complexly according to professional category, degree of autonomy, position in the care chain and specific function performed. Effective defense requires knowing the particularities of each profile: the experienced specialist responds for their autonomous decisions; the MIR enjoys mitigated liability when acting under tutelage; nursing responds directly in their professional autonomy scope; the anesthetist has a very specific liability profile due to intraoperative control.

Criminal Regime by Professional Category

There is no single "duty of healthcare care": each professional category responds according to what it could and should do in its position. The criminal types are common —fundamentally homicide by negligence (Art. 142 CP) and injuries by negligence (Art. 152 CP), with professional disqualification as an accessory penalty—, but their application depends on the professional's level of autonomy. The specialist responds for their autonomous decisions; the resident, in a mitigated way under supervision; nursing, in its own field of care; the anesthetist, for intraoperative control. Determining precisely which decisions corresponded to each one is therefore the starting point of any defense.

The MIR and Trust Doctrine

The Resident Physician is in training and works under tiered supervision. Case law mitigates their criminal liability when: (1) they acted within the autonomy level of their residency year, (2) consulted or attempted to consult their tutor in cases exceeding their competence, and (3) the pathology or complication was not recognizable for a professional of their training level. Principal liability shifts to tutor or supervisor when there is culpa in vigilando.

Nursing: Professional Autonomy

Nursing is not a mere executor of medical orders: it has its own field of professional autonomy —care, patient identification, correct administration of prescribed medication, monitoring and nursing discharge— and responds directly for errors committed within it. By the same token, it does not respond for the error corresponding to the prescribing physician, unless the order was manifestly erroneous and detectable (for example, a grossly disproportionate dose or an incompatible administration route), in which case the duty to warn is activated. The defense carefully draws that border: distinguishing the nursing act from the medical act is decisive for placing the liability where it belongs.

Teamwork and Liability Distribution

Modern medicine is coordinated work: surgeon + anesthetist + nursing + technicians. The doctrine of the trust principle allows each professional to trust the correctness of the action of other team members within their own scope. Defense frequently articulates this principle: the surgeon does not respond for anesthesia error, nor nursing for erroneous prescription, unless there were objective signals that should have been detected. The practical consequence is a reassignment of liability: establishing that the error corresponded to another team member, within their sphere of autonomy, frees the defended professional.

Coordination with the Insurer

Almost all healthcare professionals have a civil liability insurance —individual, professional-association or center-based— which usually covers legal defense and eventual compensation within the policy limits. Its immediate activation is essential: notification to the insurer from the first proceeding avoids coverage problems and allows the criminal defense to be coordinated with the civil one. It is also advisable to review the concurrence of policies (the individual one and the center's) to articulate a coherent and non-contradictory defense. To this is added, as reinforcement, deontological expertise: a report from the Professional Association or scientific societies endorsing the correctness of the action.
